Microcombs, or frequency comb on microresonators have been extensively studied for more than ten years thanks to its broad spectrum and simplicity. The noise characteristic of microcomb is determined by the effective detuning. In this study, we measured the effective detuning with a network analyzer and RF beat noise to see the noise dependence on the effective detuning.
